Тест 1.3 Beam with tightener

Analytical solution: M. Laredo, Résistance des matériaux, Paris, Dunod, 1970, p. 77.

Geometry:
Стержни AD, DF, FB: А = 0.01516 м²; А_r = A/2.5; I = 2.174 x 10^-4 м⁴.
Стержни AC, DC, CE, FE, EB: А₁ = А₂ = 4.5 x 10^-3 м²; А₃ = 3.48 x 10^-3 м².
а = 2 м; b = 4 м; l = 8 м; с = 0.6 м; d = 2.088 м.

Material characteristics: Isotropic elastic, Е=2.1 х 10¹¹ Па, G=0.4 x Е Па.

Boundary conditions: uA = vA = 0; vB = 0.

Stresses:

p = -50000Н/м. The tightening is tightened on the δ = 6.52 x 10-3 м.
